Where does the horsey set go to escape the galloping masses? To Wellington, Fla., a little west of Palm Beach. It draws its name from its founding father, Charles Oliver Wellington, a New York accountant and investor who drained flood-prone land close to the Everglades. His son, Roger Wellington, began turning it into a manicured community in the 1970s. The equestrian elite arrived shortly thereafter, lured by the gleam of the town's International Polo Club. Residents today include a movie actor, a baseball star and at least 5 billionaires, including 2 of the world's 20 richest people. Below, a glimpse at the estates belonging to these celebrities and capitalists.

If the former mayor wants to escape New York, he can withdraw to these 12 secluded acres. When he purchased the place in 2006, the 7-bedroom, 9-bath home included a 2-story living room, a cherry-paneled office and a 12-stall horse barn with owner's lounge and groom's quarters. His daughter Georgina is a noted horse lover.

Jeremy and Margaret Jacobs

$6.9 million

(2015 total market value)

The couple's presence in Wellington goes back more than three decades; most recently the billionaire (who's chairman of hospitality company Delaware North) and his wife busily spruced up their Deeridge Farm so it could host part of a worldwide horse-jumping competition.

Jarrod Saltalamacchia

$2.7 million

(2013 sales price)

As his tenure with the Boston Red Sox wound down in fall 2013, Saltalamacchia picked up a 4-bedroom, 4-bath home with gold-leaf ceiling, marble floors and a 1,000-bottle wine cellar. It's in the Aero Club, a neighborhood of 248 houses with its own private airstrip. That's convenient for making it back north--he's a Detroit Tigers catcher now--in time for batting practice.

The Campbell Soup heiress already had four Wellington properties before she purchased almost 50 more acres last December. It's reportedly an estate complete with a track and stables as well as a separate dairy farm. Up north she's the president of Iron Spring Farms, a horse-breeding center west of Philadelphia.

John and Leslie Malone

$892,352

(2015 total market value)

The Liberty Media chairman and his wife have a (modest-for-Wellington) manse in a ritzy subneighborhood, Estates of Hunter's Chase. Located within the Palm Beach Polo Golf & Country Club, the community has 2 18-hole courses, 11 polo fields, 10 tennis courts and a croquet lawn. In addition to their house, the couple owns some 50-plus acres nearby, which they reportedly use as a horse farm.

Murray and Therese Kessler

$2.6 million

(2015 total market value)

Why would Murray Kessler, Lorillard's former CEO, have land down here? It might have something to do with his daughter, Reed, an Olympian who competed in horse-jumping and

more recently rode in an annual Wellington horse festival.

Tommy Lee Jones

$19.9 million

(list price)

Enough room for an entire herd: The equestrian-focused estate has 48 stalls with all the necessary trappings (seven tack rooms, a fly-spray system) to keep the creatures in pristine shape. (It also includes a polo field.) For the people doing that work, there are 4-bedroom, 2-bath staff quarters. The Oscar-winning actor has another property a few miles away.

Bill Gates

$7.5 million

(2015 total market value)

The world's richest man bought one Wellington home in 2013--a 4-bedroom, 4-bath with 10-foot mahogany front doors--before purchasing another property on the same cul-de-sac in March. (Gates controls neither property under his own name; each is technically owned by a trustee connected to him.)
